<p>Thanks for the clarification. It is completely impossible for WAL mode since that uses shared memory. I must have conflated that with non-WAL mode in my mind.<p>From <a href="https://sqlite.org/wal.html" rel="nofollow">https://sqlite.org/wal.html</a><p>> All processes using a database must be on the same host computer; WAL does not work over a network filesystem. This is because WAL requires all processes to share a small amount of memory and processes on separate host machines obviously cannot share memory with each other.</p>

<p>As others have pointed out the electricity price is only set by gas when gas is needed, but that's only part of your bill. Renewables now make up over half of UK electricity generation and they are financed through Contracts for Difference which are ultimately paid for by a supplier obligation levy on electricity bills.<p>When market electricity prices are lower than the strike price for a CfD, electricity users end up paying the difference through the levy and when the market price is higher it reduces the amount levied. So for the renewable portion of UK electricity generation we effectively pay the fixed strike price of the CfD whatever the market price.</p>

<p>The orange peel is going to decompose and produce CO2 either way. Methane is produced when there is not enough oxygen available while decomposing, which certainly seems a possibility if it's dumped in big piles.</p>

<p>Again opportunity costs. It almost always makes sense to spend the money on the most efficient means to achieve the goal. Money spent paying farmers and ethanol refiners to inefficiently produce 25% lower carbon fuel could instead be directed at other endeavours that for the same cost reduce carbon emissions more.</p>

<p>Opportunity costs essentially. The effort that goes into growing and refining corn ethanol could be better spent on reducing fuel consumption instead of dedicating five acres of land to provide the equivalent net yearly fossil fuel consumption of a single average car using 500 gallons of gasoline to drive about 15000 miles.</p>

<p>The problem is corn requires a lot of fossil fuel energy input, mostly in the form of fertiliser. The net energy output is only around 1.3 so an acre of corn produces maybe 400 gallons of gasoline equivalent output requires 300 gallons of gasoline equivalent in energy inputs.<p>Ethanol from sugarcane makes a lot more sense. Corn ethanol is just a wasteful subsidy for farmers paid for by drivers.<p><a href="https://en.wikipedia.org/wiki/Ethanol_fuel_energy_balance" rel="nofollow">https://en.wikipedia.org/wiki/Ethanol_fuel_energy_balance</a></p>

<p>I can get somewhat close from the Census Person Income in 2017 all data tables:<p><a href="https://www.census.gov/data/tables/time-series/demo/income-poverty/cps-pinc/pinc-01.2017.html" rel="nofollow">https://www.census.gov/data/tables/time-series/demo/income-p...</a><p>That has numbers of people in $2500 income intervals. Calculate people in interval * 1/(income/minutes per year) for each interval sum and divide by total with income and I get an average poverty of 49 minutes.<p>I think he might be using after tax income and may be calculating based on household income/household members or similar instead which would explain the discrepancy (since children don't work).</p>

<p>Life in the US is definitely more precarious than in Europe but that has been the case for a long time while median real earnings after stagnating from about 2001 to 2015 have been growing well since then.<p><a href="https://fred.stlouisfed.org/series/LES1252881600Q" rel="nofollow">https://fred.stlouisfed.org/series/LES1252881600Q</a><p>There is a huge mismatch between perception and data.

<p>Average != median. This measure seems to be so high because there are so many low paid workers in the US due to low minimum wage.<p>Median workers in the US have some of the highest hourly wages at PPP in the rich world and they have been increasing, but they are pretty similar to those in Germany. The big difference in annual pay at PPP is down to hours worked.<p>For 2022 average annual hours worked per worker in the US is 1790 while in Germany it is 1340 [1]. Meanwhile average hourly wages at PPP in US are $34.9 vs $34.6 in Germany [2]<p>[1] <a href="https://ourworldindata.org/grapher/annual-working-hours-per-worker" rel="nofollow">https://ourworldindata.org/grapher/annual-working-hours-per-...</a><p>[2] <a href="https://ourworldindata.org/grapher/average-hourly-earnings" rel="nofollow">https://ourworldindata.org/grapher/average-hourly-earnings</a></p>

<p>I'm not convinced we'll ever see mass deployments of batteries to homes, not because of the fossil fuel lobby but because of the economies of scale from installing grid sized batteries at strategic points in the transmission network.<p>In California grid scale batteries have capital costs of around $125/kWh to $155/kWh while a home battery might be 20x that including installation.</p>

<p>The value of the metals will depend a lot on the battery chemistry. LFP batteries don't need nickel or cobalt and sodium-ion batteries can also replace the expensive copper foil on the anode with cheaper aluminium foil.<p>I'm somewhat sceptical that used batteries will ever be worth much other than as scrap given the cost and complexity in testing, installing, and managing a mixed set of used batteries in larger installations.<p>With new batteries halving in price every 4 years or so the value of the raw materials in old NMC batteries alone should make it economical to sell for scrap and buy new batteries for stationary use cases after 10 years or so!</p>
